Getting my feet wet with Survey123 Connect. I wanted to physically reformat a survey so that the sections in it flow the same way as a paper form it will replace. I'm slowly copy/pasting items from the original XLSForm into a brand new one and I'm getting this error:

Unless I missed it, I didn't see this error in the documentation or through searching the group. I've attached the XLSForm that's generating this issue.
Thanks!
